Up to now biodegradable bone implants with the ability of bearing high loads for the temporary replacement of bones or as osteosynthesis material are not available. Iron and iron based alloys have been identified as appropriate materials, since they

Two types of new cellular metals are fabricated by assembling layer by layer helically-formed wires with metal hollow sphere (MHS) arrays. In the finished configuration, the MHSs are located in small tetrahedrons or octahedrons of the inner space of

Melt extraction is a near-net-shape casting process in which a swiftly rotating disc draws filaments out of a melt. The melt solidifies at the V-shaped circumferential edge upon first contact, and the layer grows while the disc moves further through

Novel Metallic Hollow Sphere Structures

Autor: Olaf S. Andersen, Bernd Kieback, Lothar Schneider, Ulf Waag, Günter Stephani

Publikováno v: Scopus-Elsevier

The obvious advantages of metallic hollow sphere materials have lead to several attempts to produce such structures. None of these approaches has gained practical significance owing to the very high cost of the methods. A new powder metallurgical pro
